Embeds: Introduce embed templates into the template hierarchy via theme-compat.

Splits wp-includes/embed-template.php, introduced in 4.4, into five new templates that can be individually overridden by themes:

  • embed.php
  • embed-404.php
  • embed-content.php
  • header-embed.php
  • footer-embed.php

Also introduces a new template tag for outputting the site title, the_embed_site_title().

The five new templates live in theme-compat, allowing for graceful fallbacks should themes prefer not to override any or all of them.

Props swissspidy, imath, ocean90, DrewAPicture.
